The former The Wanted singer attended a performing arts school, but insisted that he would be “car crash” without professional partner Aliona Vilani.
Speaking to Hello magazine about ‘Strictly’, Jay said: "I have some basic advantages, because as a kid, I did some dancing.
"I'd do tap and ballet after school - really cool at that age - and then at 16, I did three years of musical theatre.
"But that was ten years ago and now I'm learning styles I've never done before. Believe me, without Aliona, it would be car-crash."
Jay and Aliona have been one of the couples who have impressed most on the current series of the BBC ballroom show, and scored an impressive 34 points on Saturday’s (31 October) Halloween special.

Despite this, Jay and Aliona are sit the current favourites to win the competition, with Boyle Sports listing him at 8/11, behind Peter Andre at 11/2.
‘Strictly Come Dancing’ continues on Saturday on BBC One.
